Membranes with recombination catalyst for hydrogen crossover reduction: water electrolysis
(ECS, 2018)An unusual morphology of the Pt-based catalyst, embedded in a PFSA membrane matrix, is described. The catalyst was developed for reducing hydrogen gas crossover in the PEM water electrolysis process. A modified electroless ... -
Metabolomics and personalized medicine
(Elsevier, 2016)Current clinical practice strongly relies on the prognosis, diagnosis, and treatment of diseases using methods determined and averaged for the specific diseased cohort/population. Although this approach complies positively ... -
Metal ions adsorption affinity of clayey materials from the North West Province of South Africa
(CUMTP, 2014)Local clays that are abundant in the periphery of Potchefstroom in South Africa were characterized and investigated as potential sorbents for the removal of metal ions from effluents. The clay samples mostly contained ... -
Methodological variables in the analysis of cell-free DNA
(Springer, 2016)In recent years, cell-free DNA (cfDNA) analysis has received increasing amounts of attention as a potential non-invasive screening tool for the early detection of genetic aberrations and a wide variety of diseases, especially ... -
A methodology to determine best-suited waiting-time periods for turbine start-up under fluctuating resources
(IEEE, 2019)— It is not uncommon for engineering process plants to comprise energy recovery. When power generation takes place under such circumstances, the nature of interlinked processes may result in fluctuating resource availability. ... -
Microgrid energy management through levelized cost of energy metric
(IEEE, 2020)The abundance of solar energy in Africa provides the ideal opportunity to mitigate the concerns on price, reliability and voltage quality of electricity supply to end-users. Rooftop PV and local energy storage solutions ... -
The millisecond pulsar contribution to the rising positron fraction
(Sissa Medialab, 2016)Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed by PAMELA and AMS−02. The Fermi Large ... -
Mineralogical observation made during the kinetic dissolution study of chalcopyrite mineral in sulphate media under free pH at room temperature
(EARET, 2018)An attempt to determine the various phenomena at play and leaching mechanism of chalcopyrite dissolution, was conducted on a chalcopyrite concentrate. The study was performed at atmospheric conditions (room temperature) ... -
Mobile phone addiction among students’s at a South African university
(The Global Business and Technology Association, 2013)The paper presents the results of research carried out to examine mobile phone addiction among students at a South African University. The results suggest that students exhibited addiction tendencies. Of the top sources ... -
Modeling and maximum likelihood fitting of gamma-ray and radio light curves of millisecond pulsars detected with Fermi
(Fermi, 2011)Pulsed gamma rays have been detected with the Fermi Large Area Telescope (LAT) from more than 20 millisecond pulsars (:\ISPs), some of which were discovered in radio observations of bright, unassociated LAT sources. We ... -
Modeling and validation of losses due to unbalanced loading of stand-alone generators
(IEEE, 2017)The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ... -
Modeling high-energy and very-high-energy γ-rays from the Terzan 5 cluster
(Fermi, 2011)The Fermi Large Area Telescope (LAT) has recently detected a population of globular clusters (GCs) in highenergy (HE) γ-rays. Their spectral properties and energetics are consistent with cumulative emission from a population ... -
Modeling light curves of the phase-aligned gamma-ray millisecond pulsar subclass
(Fermi, 2011)The gamma-ray population of millisecond pulsars (MSPs) detected by the Fermi Large Area Telescope (LAT) has been steadily increasing. A number of the more recent detections, including PSR J0034−0534, PSR J1939+2134 ... -
Modeling of gamma-ray millisecond pulsar light curves revealed by Fermi-LAT
(Thê Giói Publishers, 2009)Fermi Large Area Telescope (LAT) has recently detected 8 gamma-ray millisecond pulsars (MSPs), providing an unprecedented opportunity to probe the magnetospheres of these lowspin-down pulsars. We performed 3D emission ... -
Modeling the pulse profiles of millisecond pulsars in the second LAT catalog of γ-ray pulsars
(AIP, 2012)Significant γ-ray pulsations have been detected from ∼40 millisecond pulsars (MSPs) using 3 years of sky-survey data from the Fermi LAT and radio timing solutions from across the globe. We have fit the radio and γ-ray pulse ... -
Modelling energy-dependent pulsar light curves
(Cambridge Univ Press, 2018)In recent years, surprise discoveries of pulsed emission from the Crab and Vela pulsars above 100 GeV have drawn renewed attention to this largely unexplored region of the energy range. In this paper, we discuss example ... -
Modelling energy-dependent pulsar light curves due to curvature radiation
(Sissa Medialab, 2017)Pulsars emit pulsed emission across the entire electromagnetic spectrum and their light curve phenomenology is strongly dependent on energy. This is also true for the gamma-ray waveband. Continued detections by Fermi Large ... -
Modelling of convection heat transfer in ducts in 1D systems codes
(IHTC, 2018)Convection heat transfer between a solid and a fluid plays a crucial role in amongst others ducts in heat exchangers, the riser tubes in reactor cavity cooling systems and between the graphite and coolant channels in the ... -
